The side wall of the blanking cylinder body 1 is provided with a feed inlet 11. A movable sealing plug 4 is arranged inside the blanking cylinder body 1, and the sealing plug 4 can seal the feed inlet 11. A sealing cover 3 is connected below the sealing plug 4, and the sealing cover 3 can seal the bottom opening of the blanking cylinder body 1. A lifting device 2 capable of driving the sealing plug 4 is installed at the top of the blanking cylinder body 1, and the lifting device 2 is provided with an adjusting block 21 for adjusting the lifting distance.

[0025] In this embodiment, the lifting device 2 includes a lifting rod 22 and a lifting cylinder body 23. The lifting rod 22 penetrates through the lifting cylinder body 23. Threads are provided at both ends of the lifting rod 22. The adjusting block 21 is installed at the top end of the lifting rod 22, and the adjusting block 21 is threadedly connected to the lifting rod 22. By adjusting the position of the adjusting block 21 on the lifting rod 22, the lifting distance of the lifting device 2 can be adjusted.

[0026] A piston 24 is arranged on the lifting rod 22, and the piston 24 is movably arranged in the lifting cylinder body 23. The edge of the piston 24 is in sealing contact with the inner wall of the lifting cylinder body 23. Connectors 25 are provided on the upper and lower sides of the lifting cylinder body 23 for introducing a medium to push the piston 24 to move. The sealing plug 4 successively includes a top connection section 41, a sealing section 42, and a bottom connection section 43 from top to bottom.
